A video signal conversion method includes: receiving an input signal from a video source; extracting an image metadata from the input signal; determining whether the input signal corresponds to a high dynamic range (HDR) imaging format according to at least one format information of the image metadata and determining whether a video receiver supports the high dynamic range imaging format; in response to the input signal corresponding to the high dynamic range imaging format and the video receiver being not support the high dynamic range imaging format, generating a conversion command; receiving, by a video processor, the conversion command; converting, by the video processor, the input signal into an output signal corresponding to a standard dynamic range (SDR) imaging format according to the conversion command; sending, by the video processor, the output signal to the video receiver; and receiving by the video receiver, the output signal in SDR imaging format.
